Can posture analysis point towards curve progression in scoliotic subjects?

Summary:Previous research employing biomechanical measurement has demonstrated asymmetries in kinematics and kinetics. Similar asymmetries have been reported from anthropometric studies. These findings suggest that asymmetry may play an important aetiological role in adolescent idiopathic scoliosis (AIS). The present study is a part of a wider comprehensive investigation aimed at identifying asymmetries in lower limb kinematics and pelvic and back movements during level walking in a sample of scoliotic subjects. Such asymmetries may be related to the spinal deformity. While previous studies indicate that force platform measurements provide a good estimation of the static balance of individuals, there remains a paucity of information on dynamic balance during walking. There is published evidence on the use of Centre of Pressure (CoP) and net joint moments in gait assessment. Although these investigations have assessed Centre of Mass (CoM)-CoP distance relationships in clinical conditions, there is a paucity of data relating to the moments about CoM. An objective of the present study was to assess and establish the asymmetry in the CoP pattern and moments about CoM during level walking and its relationship to spinal deformity. Results indicate differences across the subjects depending on the laterality of the major curve. Furthermore, the results indicate that the variables identified in this study could be applied to initial screening and surgical evaluation of scoliosis and other spinal deformities. Further studies are being undertaken to validate these findings.
